BACKGROUND ART

Recently, there have been many efforts to develop fishing equipment withunderwater image photographing systems, which would enhance theexperience by allowing the user to observe the underwater environment byway of the video system attached to the fishing equipment.

For example, the Korean Patent Publication of registration No.1988-76867 discloses fishing equipment that enables the user to watchimages sent from underwater video camera to an external display devicethrough electric wire while staying out of water.

But in reality, this concept is still not on a practical level, thusthings like fishing while observing the underwater conditions andenvironment hasn't come true yet.

That is because all underwater photographing and transmitting systemincluding fishing equipment with image system require some kinds ofchannels that can send and receive signals. These channels are needed tosend underwater image signals out of the water and receive these signalsto display them on the display device. Of course, it is impossible touse the conventional fishing lines or general electric wires for thispurpose. In other words, to construct fishing equipment with underwaterimage photographing system, the cable has to be thin, durable, andflexible at the same time in order to send/receive various signalsincluding image signals.

The present invention is designed to provide a multifunctional cablethat has all the characteristics needed in a fishing line such asfineness, flexibility and durability, and also has the capability ofsending/receiving of electricity and image signals as mentioned above.Another purpose of the present invention is to provide fishing equipmentwith video system and underwater image video system using the abovementioned multifunctional cable, which enables the user to photographthe underwater environment and fish effectively.

FIG. 1 is a cross sectional view of the internal structure of themultifunctional cable according to one preferred embodiment of thepresent invention. As shown in FIG. 1, the multifunctional cable 10according to the present invention has two strands of electric cords 11that channel electricity, a image signal cord 12 that channels imagesignals and a control cord 13 that channels control signals inside, allof which have inner coats 11 c, 12 d, 13 d on their surfacesrespectively, arranged in a stable manner; and the outside of abovecords is molded with flexible and durable molding resin 14; and outersurface of the molding resin is coated with an abrasion resistantexterior coat 15 again.

The image signal cord 12 and control cord 13 have inner lines 12 a, 13 aand outer lines 12 b, 13 b respectively; and insulating layers 12 c, 13c are formed between them; The electric cords 11 also have the innerlines 11 a and outer lines 11 b, but do not have insulating layersbetween them 11 a, 11 b.

Also as shown in FIG. 1, it is desirable to apply different diameters tothe electric cords 11, and, image signal cord 12 and control cord 13inside the cable 10, thereby prevent the cords 11, 12, 13 from gettingtwisted.

The multifunctional cable 10 needs to be light and durable like thefishing line and must be able to channel electricity and signals at thesame time. So a recommended specification of multifunctional cablesuitable for standard specifications of a high definition CCD DC 12V,250 mA may be as shown in Table 1. TABLE 1 Image Signal Cords/ Item UnitControl cords electric cords Number of cores number 1 Each 2 Inner LinesMaterial Silver Plated Copper Tin Plated Copper Diameter mm 0.12 0.306Insulating Material Teflon Layer Diameter mm 0.307 Outer Lines MaterialTin Plated Copper Tin Plated Copper Thickness mm 0.03 0.65 Inner coatMaterial Teflon PE or PP Diameter mm 0.46 Molding Diameter mm 0.92 ResinMaterial Kevlar or Kevlar or Carbon Resin Carbon Resin Exterior coatMaterial PE or PP Diameter mm 1.5

According to Table 1, the recommended materials for the cords used inthe multifunctional cable according to the present invention are; Tinplated copper for the electric cords 11, silver plated copper for theinner line 12 a, 13 a and tin plated copper for the outer line 12 b, 13b of the image signal cord 12 and control cord 13 are used, and a Tefloninsulating layer 12 c, 13 c is formed between said inner lines 12 a, 13a and outer lines 12 b, 13 b.

The electric cord 11 formed as above uses polyethylene (PE) orpolypropylene (PP), and the image signal cord 12 and control cord 13 useTeflon to form an inner coat and complement the insulation and hardness.

These electric cords 11, image signal cord 12 and control cord 13 areunited using molding resin 14 or the voids between the cords 11, 12, 13are filled with molding resin 14 having flexibility, excellent tensileproperties and high durability like Kevlar fibers or carbon resin, then,the exterior coat 15 is formed using abrasion-resistant and flexibleresin like polyethylene or polypropylene.

By using the structure and material composition mentioned above, it ispossible to make the multifunctional cable 10 according to the presentinvention have a total cable diameter of 1.5 mm, an electric cord 11have a diameter of 0.306 mm, an image signal cord 12 and control cord 13have a diameter of 0.12 mm, and still have the characteristics of aelectric cord and flexibility and durability at the same time.

On the other hand, as stated above, the number and dimensions of theimage signal cords and control cords mentioned above may be changedaccording to its use, and this kind of change is also regarded as belongto the scope of the present invention.

Now, a preferred embodiment of the fishing equipment with video systemaccording to the present invention will be explained by referring toFIGS. 2 to 6 which show the structure of fishing equipment with videosystem according to this invention.

As shown in FIG. 2 to FIG. 6(a), (b), the fishing equipment of thisexample is composed of a photographing part (200) comprising a weight210 having a camera 220 and control device 213 inside, and a float 230,thereby photograph the underwater environment; an external device part100 comprising display panels 110, controllers 120 and electric powersuppliers 130, thereby display images taken by the photographing part200 and control the control devices 213; and a multifunctional cable 10that connects the devices mentioned above.

As shown in FIG. 4(b), the multifunctional cable between the weight 210and float 230 of the photographing part can be cut, and a connecter 20a, 20 b can be installed to connect two ends of the cut multifunctionalcable. This make it easy for the user to change the weight 210 wheneverneeded.

Also, the weight 210 of the photographing part 200 may be made invarious shapes. As shown in FIG. 4(a) and (b), bisected case shape 211and known lure shape case 211 may be desirable.

The bisected case shape 211 mentioned above has a hinge 21 la on onepart, a fixing flange 211 b on the other part, and two parts of the caseare combined together by using a fixing bolt 211 c. A Lure shape 211′means that the case of the weight has lure shape, and when this type ofweight shape is adopted, the camera 212 should be placed in the back sothat the attack of fishes cannot destroy the camera.

As shown in FIG. 3, it is possible to outfit several tying rings 215 andfixing grooves 216 on the surface of the case 211, which help the tyingof the fishing line 10 and fishhook and installing of the lightingsystems 220. And inside of the case, a camera 212 for underwaterphotographing and control devices 213 are built in.

One or several devices can be chosen and attached together selected fromthe group of built-in camera, supersonic wave sensor, digitaltemperature sensor, underwater mike, pressure sensor, vibrating motor,geomagnetic sensor and camera angle adjustor as the control device 213.With these control devices 213, the user can check the temperature,pressure, depth, current and sound of the water and find a school offish from outside of the water. And by using the camera angle adjustor,the user can control the angle of the camera and shot the underwaterenvironment much more precisely.

Among the control devices mentioned above, the digital temperaturesensor, underwater mike, pressure sensor, vibrating motor, andgeomagnetic sensor can be one of the known micro type devices; whereinsensing parts of the pressure sensor, temperature sensor, andgeomagnetic sensor should be exposed to the surface of the weight casebecause they need contact with water.

Especially as shown in FIG. 4(b), if a vibrating motor 213 b isinstalled as a control device 213 to the lure shaped weight 211′, thelure shaped weight 211′ swims under the water according to the vibrationof the vibrating motor 213 b and this allures the carnivorous fishesbecause this lure formed weight 211′ may seem like a real live fish tothem.

Also, as shown in FIG. 4(a), the camera angle adjustor is built byinstalling the

shaped fixture 219 driven by a motor 218 installed inside the weight210, as to place each end of the fixture at each end of the weight caseon the upper part of the weight. So the camera angle is adjustable toany angle by the drive of the above mentioned fixture 219 by controllingthe rotating direction of the motor 218 through the controller 120 ofthe external device part 100.

Also, in this invention, the case 211 of the weight 210 mentioned abovehas different density to prevent the current to shake the camera and toknock it off focus. In this example, the bottom part is filled withhigh-density material 214 a, a camera 212 and control system 213 arebuilt in the middle part, and an empty space 214 b is formed in theupper part as shown in FIG. 3. The difference of the density of eachpart makes the weight 210 always stand under the water.

And as shown in FIGS. 5(a) and (b), It is possible to equip a underwaterfloat between the weight 210 and buoyancy regulating float 230 connectedby the multifunctional cable 10, thereby prevent the weight 210 fromfluctuating, and to hang one or more supplementing weight 219 to thering 218 attached to the bottom of the weight, thereby make it easy toregulate the density and the diving depth of the weight 210.

Lighting 220 provided for this weight 210 is composed of an illuminator221 a, 221 b, batteries 222 and a switch 223 inside a sealed case 224 asshown in FIG. 4. One or more illuminators can be chosen and attachedfrom the high luminance illuminating diode 221 a or the infrared light221 b according to the use.

On the case 224 mentioned above, there are fixing holes 225corresponding to the fixing grooves 216 formed on the weight 210's case211, so that they can be connected together with bolts.

The weight 210 and float 230 are connected together by themultifunctional cable 10 according to the present invention. And asshown in FIG. 3 and FIG. 4(a), certain length of flexible tube 217 b orthin wire 217 a is installed, which allows the location of the cameraangle and fishhook to be adjustable.

If the user bends the flexible tube 217 b or thin wire 217 a to acertain degree before putting the photographing part 200 under thewater, the camera 212 in the weight 210 forms a fixed shooting angleunder the water, and the fishhook also stays at a certain point underthe water.

As shown in FIG. 6(a), the external device part 100 connected to thephotographing part 200 mentioned above, is composed of a display panel110, controller 120 and electric power supplier 130, thereby displaysimages shot by the photographing part 200, operates the control devices,and supplies electric power to the devices. Wherein, the controller 120,display panel 110 and electric power supplier 130 may be integrated formor separate form. And, the external device part may be attached to thefishing pole and integrated with it as shown in the present example, ormade separately from the fishing pole as a separate equipment

As shown in FIG. 6(b), if these devices of external device part 100 areused separately from the fishing pole, the external device part 100 canbe composed effectively with the known mobile phone with power supplyunit, display unit, input unit, image storage unit and control unit, byadding a connector to connect with the end of the multifunctional cable,or by installing a radio sending/receiving circuit 334 which exchangesignals such as image signal with the wireless radio sending/receivingfloat of the photographing part or the wireless transceiver inside, orby adding or installing both of the above mentioned means to be usedoptionally by the user. In this case, the underwater images sent to themobile phone can be sent to other places via mobile Internet and so on.And it is also possible for several people to watch underwater imagesfrom different spots by installing several external device parts 100.

And, the above mentioned electric power supplier 130 is composed ofknown adaptor and batteries, and the well-known technology related tothe display technology can be applied to the construction andinstallation of external device part 100 especially power supplier 130,so the detailed drawings and explanations are omitted in thisspecification.

The photographing part 200 and external device part 100 with the abovementioned constructions are connected with each other by different meansaccording to the communication type. If the wireless radio communicationsystem is adapted, the photographing part 200 and external device part100 with radio sending/receiving circuits 231 having an electric powersupplier, are connected with each other by normal fishing lines as shownin FIG. 5(a). But if the wire communication system is adapted, thephotographing part 200 and external device part 100 without radiosending/receiving circuits 231, are connected with each other bymultifunctional cables according to the present invention, therebychannel signals and electric power through them.

On the other hand, if a little modification is added to these devices,it is possible to compose a fishing equipment with wireless type videosystem by equipping an individual wireless transceiver 333 having afirst radio sending/receiving circuit, and connecting it with buoyancyregulating float of the photographing part 200 similar to that of abovementioned wire type, and then attaching it to one spot out of the water,desirably to a spot on the fishing pole, more desirably to a spot on thegrip part of the fishing pole and making the other devices of theexternal device part 100 such as controller, display panel into portabletype with a second radio sending/receiving circuit inside, so that saidradio sending/receiving circuits (the first and second radiosending/receiving circuit) communicate with each other.

Addition to the above mentioned construction, by forming an inlet hole141 and an outlet hole 142 on the fishing pole at the starting point andextruding point of the cable respectively, thereby make themultifunctional cable 10 pass through inside the fishing pole. Byadapting this structure, it is possible to prevent the cable 10 gettingtangled outside the fishing pole, and to make it easy to carry with.

FIG. 7 shows the usage state view of a complete construction of thewireless type underwater image video system according to a preferredembodiment of the present invention; and FIG. 8 is a cross sectionalview of the photographing device of the underwater image video systemaccording to the present invention. Now, the desirable example of theunderwater image video system according to the present invention will bedescribed by referring to FIGS. 7 to 8

The underwater image video system according to the present example iscomposed of a photographing part 300 comprising a photographing device310, winding reel 320, control devices 312 and a buoy 330 thereby takepictures of underwater environment, and a external device part 400comprising display panels, controllers and an electric power suppliersthereby display images taken by the photographing part 300 and controlthe control devices 312.

As shown in FIG. 8, the photographing device 310 has fixing grooves 313on the surface so as to install the lighting devices 314, and camera 311for photographing underwater environment, control devices 314 such assupersonic wave sensor, digital temperature sensor, underwater mike,pressure sensor, geomagnetic sensor and camera angle adjustor similar tothe weight 210 of the above mentioned fishing equipment with videosystem.

Addition to the above structure, the photographing device 310 has afixing clip 317 and a twin lens reflex 316 outside of the device 310 tocarry out more effective photographing. The fixing clip 317 is for theeasy attaching/detaching of the photographing device 310 to the divingapparatus, so that the diver moves freely under the water without anyrestriction due to the photographing device 310. And the twin lensreflex 316 helps the diver to keep focus easily and to adjust the framewith observing the image being taken by the camera under the water.

As shown in FIG. 8, the twin lens reflex is composed of a case 316 a, ahinge 316 b to connect the cases and a reflector 316 c. The case 316 ahas the shape of each end open to make it possible for the light to comein and out through the case, and has a curved part between the two ends.A hinge 316 b is installed on the curved part for the case to be foldedfreely. And a reflector 316 c is installed inside the case on the curvedpart, thereby the incident ray can be reflected and escape from the caseto a certain degree. With the construction described above, the user canadjust the focus and frame of the camera 311 after observing the spotwhere the camera 311 is taking pictures through the twin lens reflex316.

The photographing device 310 and the buoy 330 floated on the surface ofwater are connected with each other by the multifunctional cable 10according to the present invention. Additionally, a winding reel 320 canbe prepared between the photographing device 310 and the buoy 330 tomake it easy for the diver to control the length of the multifunctionalcable 10 according to the diving depth. To help the easyattaching/detaching of the winding reel 320 to the diving suit, it isdesirable for the winding reel 320 to have a clip or so.

The external device part 400 connected to the photographing part 300 canbe constructed similarly to that 100 of the fishing equipment with videosystem, and the functions of the devices are same for the most part, sothe additional drawings and detailed explanations are omitted in thisspecification.

On the other hand, a kind of communicating path is necessary to exchangesignals between the photographing part 300 and external device part 400.In this example, radio sending/receiving circuits are installed insidethe buoy 330 and the external device part 400, which exchangeinformation by wireless type.

FIG. 10 shows the structure of a buoy 330 including radiosending/receiving circuit with electric power supplier 332 inside.

But, in the case that the photographing part 300 and external devicepart 400 are connected by a cable, there is no radio sending/receivingcircuit in the buoy 330, and the electricity and signals are exchangedby using the multifunctional cable according to the present invention.

Also, although we have explained the cases where radio sending/receivingcircuits were built in, but when the diver simply sends image signalsand other underwater signals to the external device part 400, evensimple type such as radio transmitting circuit is installed in the buoy330 and radio receiving circuit is installed in the external device part400 will be sufficient. These kinds of structure are also considered tobe in the scope of this invention.

If the wireless type is adapted for the communication, it is possible touse general radio frequency, but it is more desirable to construct anetwork of 2.4 GHz radio circuit, and use several channels provided bythe 2.3 GHz radio circuit network mentioned above to observe theunderwater images taken by several divers at the same time.

Although we have explained about the example of wireless type underwaterimage video system with radio sending/receiving circuits, instead ofusing radio sending/receiving circuits mentioned above, it is possibleto connect the buoy and the external device part 400 using themultifunctional cable according to the present invention and exchangesignals through this cable. In this type of system, the other componentsexcepting the radio sending/receiving circuit explained with thewireless type underwater image video system can be applied unchanged.

Also, the display and control functions using mobile phones on thefishing equipment with video system can be applicable.

Only some examples on how to use the multifunctional cable, the fishingequipment with video system and underwater image video system areexplained above. But this description is not everything, and all simplemodifications made to the technology concerning this invention are inthe range of this invention.
